The VSS is attached to the transmission, the best way to replace it is to first disconnect battery cable. Then raise and safely support vehicle. Detach the electrical wiring from the VSS then unbolt the VSS from mounting location.

What is the sensor on the rear axle called?
I went to parts store he said it was a brake sensor of some type.
He also sold me a vss and said it was located on the side of the trans.
I do not have much faith in a parts guy, but I really would like to know where that vss is located, maybe a diagram?
Thanks riley

It is simply called the rear axle sensor, some may call it a rear speed sensor, should have a red/pink and a light green/black wire running to it. It is part of the ABS that also works as a VSS. I'm not certain why the parts place sold you a VSS for, I am 99% positive that there is no separate VSS on this vehicle aside from the rear axle sensor.
